Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This vulnerability is a use-after-free issue in Google Chrome's DevTools. It occurs when a program tries to use memory that has already been freed, potentially allowing a local attacker to execute arbitrary code outside the sandbox via a local program.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 153.0.8010.36. To detect it, check your Chrome version by running chrome://version/ in the browser address bar. If your version is below 153.0.8010.36, the system is vulnerable.

Impact Analysis

An attacker could exploit this to run malicious code on your system, potentially gaining control over your device or accessing sensitive data. Since it affects DevTools, it may also allow unauthorized debugging or monitoring of your browser activities.

Compliance Impact

This vulnerability allows a local attacker to execute arbitrary code outside the sandbox via a local program. Such arbitrary code execution could potentially lead to unauthorized access to sensitive data, which may violate compliance requirements under GDPR (data protection) and HIPAA (health information privacy).

Mitigation Strategies

Update Google Chrome to version 153.0.8010.36 or later to address the use after free vulnerability in DevTools.
